Just entered 5+ years of long term weight maintenance after 40 years of yo-yo and morbid obesity. Maintaining 70+ pounds, LCHF/Keto/Paleo/Modified AIP
I also know that I have a double copy of the “sprinter” genes, so the chronic cardio adds an inter-tube like layer of body fat around my middle. Moderate walking 60+ mins activity on my fitbit, with my camera- read stopping sometimes to photograph works well.
For others in long term weight maintenance (Refuse to Regain book author and lower carb champion Barbara Berkeley, MD) she needs more aerobic activity to maintain her weight loss.
So I do rowing Tabbata sprints on a concept 2 rower, weights 2 X per week, push-ups at home every day, and 5+ miles with 60 active mins per day. I take a rest walking day ever 10-20 days with no problems.
I sometimes hike in the mountains, kayak in lagoons and oceans, and play light tennis, snorkel a few days a year. All that activity means I eat more, but in my Keto food template. I don’t eat junk carbs due to being in food addiction remission 6+ years.
If I do no walking over 5 days just because I want to go back to my old ways, then I do start a slow, but steady regain.
Do some n=1 for weight maintenance- IMO. Your milage WILL differ. Based on lots of things. Do you and share it. Onward. Great topic!!!
